Hi Rainer, you are ahead of me in testing this (I got bogged down in fixing
libffi for i686 rust use)

Just to note that the values used in gcc/jit/Make-lang.in are still not
completely correct (and that causes problems with cross-compilers where the
target and host linkers are different)

 * because LD_VERSION_SCRIPT_OPTION and LD_SONAME_OPTION are for $target, n=
ot
$host.
 * (maybe not relevant to gm2) the .map file is not in a format usable by
Darwin's linker and unfortunately the existing conversion scripts in the tr=
ee
do not handle that specific map.

So much of the content is useful for Darwin and mingw but those points need=
 to
be taken into account (rather than copying verbatim).=
